Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite board processing technology, specifically a feeding device for composite board preparation. Background Technology
[0002] During the preparation of composite slabs, concrete needs to be poured into molds. After the concrete solidifies, composite slabs are produced. In order to spread the concrete relatively evenly in the molds, workers need to manually pull the pipes used to transport the concrete. Because pulling the pipes requires workers to walk around continuously, the labor intensity of workers is high during the continuous production process. Moreover, the spreading is not even enough, and leveling is required later, which further increases the labor intensity. Utility Model Content

Detailed Implementation
[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0016] like Figure 1-3 As shown, a feeding device for preparing composite slabs includes a concrete pump 2, a feed hopper 3 and a discharge pipe 4. A material leveling assembly is provided on one side of the concrete pump 2, comprising a fixed plate 5 and a movable plate 6. Two guide rods 7 are provided between the fixed plate 5 and the movable plate 6, and a pusher plate 8 is slidably connected to the two guide rods 7. Side guard plates 9 are provided at both ends of the pusher plate 8, and rubber plates 10 are provided on the lower surfaces of the pusher plate 8 and the side guard plates 9. The pusher plate 8 and the fixed plate 5 have openings for the discharge pipe 4 to pass through. A ball screw 12 is provided between the fixed plate 5 and the movable plate 6 through the through groove 11. A servo motor 13 for driving the ball screw 12 to rotate is provided on one side of the movable plate 6. The push plate 8 is threadedly connected to the ball screw 12. A groove is provided at the lower end of the movable plate 6. A limit plate 14 is provided inside the groove. A fixed rod 15 that is slidably connected to the movable plate 6 is provided on one side of the limit plate 14. An electric push rod 16 is provided on the movable plate 6. The output end of the electric push rod 16 passes through the movable plate 6 and is fixedly connected to the limit plate 14.
[0017] The concrete pump 2 can be one of the following: piston concrete pump 2, extrusion concrete pump 2, plunger mortar pump, diaphragm mortar pump, or screw mortar pump. An external concrete mixer truck can deliver the mixed concrete into the feed hopper 3, and the concrete pump 2 will pump the concrete out through the discharge pipe 4.
[0018] When preparing the composite plate, the mold 1 is first placed between the fixed plate 5 and the movable plate 6. Specifically, the output end of the electric push rod 16 is retracted, which drives the limiting plate 14 to move. The fixed rod 15 can improve the stability of the limiting plate 14 when it moves. After the limiting plate 14 moves a certain length, the distance between the fixed plate 5 and the limiting plate 14 increases. At this time, the mold 1 can be placed between the fixed plate 5 and the limiting plate 14, and one end of the mold 1 is aligned with the fixed plate 5. Then, the rubber plate 10 under the push plate 8 and the side guard plate 9 is aligned with the edge side of the upper surface of the mold 1. After the mold 1 is placed, the electric push rod 16 is started, and the output end of the electric push rod 16 is extended. The output end of the electric push rod 16 pushes the limiting plate 14 to move, which shortens the distance between the fixed plate 5 and the limiting plate 14. The fixed plate 5 and the limiting plate 14 are used to clamp and fix the placed mold 1.
[0019] After placing the mold 1, the concrete pump 2 is moved to one side of the fixed plate 5, and the discharge pipe 4 on the concrete pump 2 passes through the through slot 11 on the fixed plate 5 and the pusher plate 8 in sequence. Then, concrete is fed into the feed hopper 3. Next, the concrete pump 2 is started, and an appropriate amount of concrete is pumped into the mold 1 through the discharge pipe 4. After pumping the appropriate amount of concrete, the concrete pump 2 stops working and stops feeding concrete into the feed hopper 3. Then, the servo motor 13 is started, and the servo motor 13 drives the ball screw 12 to rotate. The pusher plate 8 is threadedly connected to the ball screw 12 and slidably connected to the guide rod 7, which can drive the pusher plate 8 to move linearly along the ball screw 12. The pump 8, side guard plate 9, and rubber plate 10 move and push the concrete on the mold 1 to move. During the process of pushing the concrete, the pump 8, side guard plate 9, and rubber plate 10 can spread the concrete evenly in the mold 1. When there is insufficient concrete in the mold 1, but the amount of missing is small, a certain amount of concrete can be added to the mold 1 through the rubber pump to make the concrete in the mold 1 evenly spread. If the amount of missing concrete is large, after the pump 8 moves from one side of the fixed plate 5 to one side of the movable plate 6, the pump 8 is controlled to move back to the side of the fixed plate 5. Then, the appropriate amount of concrete is pumped into the mold 1 through the concrete pump 2. Then, the pump 8 pushes the concrete again to make the concrete evenly spread in the mold 1.
[0020] The amount of concrete pumped into mold 1 by concrete pump 2 will not exceed the maximum amount of concrete required by mold 1, thereby avoiding the need to remove the concrete that has been poured into mold 1.
[0021] After the concrete in mold 1 is laid out, the retraction of the output end of the electric push rod 16 is controlled to move the limiting plate 14, increasing the distance between the fixed plate 5 and the limiting plate 14. Then, mold 1 is removed from between the fixed plate 5 and the limiting plate 14, and a new mold 1 is placed between the movable plate 6 and the limiting plate 14. The removed mold 1 is transferred to the vibration table for vibration treatment to expel the gas in mold 1 and make the concrete in mold 1 more compact.
[0022] The rubber plate 10 has a certain degree of elasticity. The rubber plate 10 is always in contact with the upper surface of the mold 1. At the same time, the time for concrete to be poured into the mold 1 is relatively short, generally about 20 seconds.
[0023] The through groove 11 is circular, and the inner diameter of the through groove 11 is 10% larger than the outer diameter of the discharge pipe 4, so as to ensure that the discharge pipe 4 can enter the through groove 11 on the push plate 8 during the process of the push plate 8 moving towards the fixed plate 5.
[0024] With the blocking effect of the push plate 8 and the side guard plate 9, the appropriate amount of concrete pumped into the mold 1 through the discharge pipe 4 will not overflow from the edge of the mold 1, so as to reduce concrete waste.
[0025] Furthermore, a right-angled positioning plate 17 is provided on one side of both the fixed plate 5 and the movable plate 6. When one side of the mold 1 can contact the two positioning plates 17 at the same time, the limiting plate 14 can be moved by the electric push rod 16 to clamp and fix the mold 1 between the fixed plate 5 and the limiting plate 14, thereby improving the installation and positioning efficiency of the mold 1.
[0026] Furthermore, a spring 18 is fitted on the fixing rod 15, and a stop block 19 is provided at one end of the fixing rod 15 to improve the stability of the limiting plate 14 when it moves and to prevent the fixing rod 15 from coming off the movable plate 6.
[0027] Furthermore, both the fixed plate 5 and the movable plate 6 are equipped with casters 20 on their lower surfaces. The casters 20 have a self-locking function, which facilitates the control of the movement of the material leveling component. When the material leveling component is in use, the casters 20 need to be in a self-locking state to ensure the normal use of the material leveling component.
[0028] Furthermore, a reinforcing plate 21 is provided between the fixed plate 5 and the movable plate 6. There are two reinforcing plates 21, and the two ends of the reinforcing plates 21 are fixedly connected to the fixed plate 5 and the movable plate 6 respectively. The ball screw 12 is located between the two reinforcing plates 21, which improves the connection stability between the movable plate 6 and the fixed plate 5, and improves the stability of the pusher plate 8 moving between the fixed plate 5 and the movable plate 6.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
